This is super useful... when it's not buggy.

The messages stay in the clipboard and make it impossible to copy anything else that is not a template from the add-on. So it's really not practical.

Unfortunately it only works on inputs but not on textareas. Can you fix this?

Exellent plugin, I like the simplicity and efficiency about it. 👍 The setup interface is easy to get, the box for the template is sized to enter a short email and the right click menu is easy to access. Thank you.

Provides an easy to use right-click menu for canned messages and responses. The only way it would be better is to be able to select some text, right click on it and then define a new template for it.
It also doesn't appear to work for some inputs.
